Steel Water Tanks – Galvanized and Stainless Steel Panel Water Tanks

Steel Water Tanks

Steel has been used for water storage for well over a century, and bolted sectional steel tanks are still specified on many projects. This range covers both hot-dip galvanized and stainless steel sectional tanks, assembled on site from pressed steel panels, sealed with food-grade gaskets and supported on a concrete slab or steel base frame.

Galvanized panels rely on their zinc coating for corrosion protection, so the coating thickness and condition matter: in coastal, high-humidity or chemically aggressive environments the coating will eventually be consumed, and zinc can leach into stored water. Stainless steel 304 or 316L avoids zinc entirely and is preferred for coastal sites and where chloride levels are elevated, but it carries a substantially higher cost than either galvanized steel or composite panels.

Where the requirement is a long-life tank with no corrosion risk at all, the same modular structure is available in SMC glass fibre panels, which cannot rust, need no coating and are lighter than steel for the same capacity.

• Bolted sectional construction in galvanized or stainless steel
• SMC panel alternative for zero corrosion risk
• Food-grade gasket sealing throughout
• Suitable for domestic, fire and process water
• Panels replaceable individually after impact damage
• Engineered base frames and access steelwork available

Applications

• Domestic cold water storage where metal tanks are specified
• Fire water reserves and sprinkler storage
• Industrial process water and cooling water storage
• Workshops, plant rooms and utility buildings
• Coastal and marine sites, using stainless steel 316L
